vtkImageCityBlockDistance Class Reference
#include <vtkImageCityBlockDistance.h>
Detailed Description
1,2 or 3D distance map.vtkImageCityBlockDistance creates a distance map using the city block (Manhatten) distance measure. The input is a mask. Zero values are considered boundaries. The output pixel is the minimum of the input pixel and the distance to a boundary (or neighbor value + 1 unit). distance values are calculated in pixels. The filter works by taking 6 passes (for 3d distance map): 2 along each axis (forward and backward). Each pass keeps a running minimum distance. For some reason, I preserve the sign if the distance. If the input mask is initially negative, the output distances will be negative. Distances maps can have inside (negative regions) and outsides (positive regions).
